Covering High Wycombe
Alongside High Wycombe, we also cover Beaconsfield, Amersham (6 miles to the north-east) and Maidenhead.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What goes into a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Design, planning drawings and structural calculations
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights
What will a wraparound extension cost?
Guide prices for wraparound extensions, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| Wraparound extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,400 to £3,800 per m² |
| Good specification | £3,800 to £4,250 per m² |
| High specification | £4,250 to £4,700 per m² |
What approvals does a wraparound extension need in England?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.
What can change the price or programme?
- Roof water from an L-shape needs careful falls and outlets.
- An open-plan space this size needs a heating plan, often underfloor heating.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
How long does a wraparound take?
Around 12 to 18 weeks on site after approvals.
